I’m wondering how to nurture a feeling of abundance? Can you share powerful questions or habits I should develop on this purpose?

I don’t specifically refer to abundance in terms of money, I really refer to the ability to consider that I’ll always have so much: so many options, opportunities, so much love, so much success, so much money, so much luck etc.

I’m been practicing this topic a bit already but I can see I still have fears of lacking or losing for instance: fear of making less money with a new job, fear of lacking time, fear of lacking money in case something terrible happens to my family, fear of losing my work-life balance with a new job etc.
